Quotation mark

Quotation marks are punctuation marks used in pairs in various writing systems to identify direct speech, a quotation, or a phrase. The pair consists of an opening quotation mark and a closing quotation mark, which may or may not be the same glyph. Quotation marks have a variety of forms in different languages and in different media.

History

The single quotation mark is traced to Ancient Greek practice, adopted and adapted by monastic copyists. Isidore of Seville, in his seventh-century encyclopedia, Etymologiae, described their use of the Greek diplé, a symbol like a right angle bracket:

The double quotation mark derives from a marginal notation used in fifteenth-century manuscript annotations to indicate a passage of particular importance (not necessarily a quotation); the notation was placed in the outside margin of the page and was repeated alongside each line of the passage. In his edition of the works of Aristotle, which appeared in 1483 or 1484, the Milanese Renaissance humanist Francesco Filelfo marked literal and appropriate quotes with oblique double dashes on the left margin of each line. Until then, literal quotations had been highlighted or not at the author's discretion. Non-verbal loans were marked on the edge. After the publication of Filelfo's edition, the quotation marks for literal quotations prevailed. During the seventeenth century this treatment became specific to quoted material, and it grew common, especially in Britain, to print quotation marks (now in the modern opening and closing forms) at the beginning and end of the quotation as well as in the margin; the French usage is a remnant of this.
